記憶效應的彩色化液晶顯示器已廣泛應用在電子書、電子 紙或其他顯示領域。傳統彩色膽固醇液晶顯示器的結構與 製作方法，使用紅(R)、綠（G)、藍(B)三層液晶堆疊結構， 搭配多種不同的驅動方式。然而，採用紅、綠、藍液晶堆 Q 疊結構造成視差現象，於製造時易造成面板結構對位不 易，增加電極設計難度及無法彎曲不便於攜帶，致使製程 複雜及製造成本過高。 因此，採用單層彩色化膽固醇型液晶顯示器的結構及 製程設計可有效避免視差、減少製程及降低成本，尤其是 用於彩色之軟性顯示器等應用領域。美國專利第US 5,825,451 揭露一種單層的彩色膽固醇液晶顯示器，利用 光可分解/聚合之旋光劑與單層膽固醇結構結合，可藉由 UV的照射，破壞或減少單一區域旋光劑的含量，進而達 6 200941073 • 到單層彩色化的效果。然而，此種顯示器易受到外界環境 光的影響，而降低其穩定性。 美國專利第US

Field of the Invention The present invention relates to a liquid crystal display device and a method of fabricating the same, and more particularly to a single-layer color cholesteric liquid crystal display device and a method of fabricating the same. [Prior Art] A β liquid crystal display (LCD) has many advantages such as small size, light weight, low power consumption, and the like. Therefore, LCDs have been widely used in electronic products such as hand-held computers and mobile phones. That is, liquid crystal display technology is continuing to develop in a light, thin, and easy to carry field. Conventional reflective color-coded liquid crystal displays with memory effects have been widely used in e-books, electronic paper or other display fields. The structure and manufacturing method of the conventional color cholesteric liquid crystal display uses a three-layer liquid crystal stack structure of red (R), green (G), and blue (B), and is matched with various driving methods. However, the parallax phenomenon caused by the red, green, and blue liquid crystal stacks of Q stacks is not easy to cause the alignment of the panel structure during manufacturing, and the difficulty in designing the electrodes and the inability to bend are difficult to carry, resulting in complicated process and high manufacturing cost. Therefore, the structure and process design of a single-layer color cholesteric liquid crystal display can effectively avoid parallax, reduce process and reduce cost, especially for applications such as color soft displays. US Patent No. 5,825,451 discloses a single-layer color cholesteric liquid crystal display that utilizes a photodecomposable/polymeric optically active agent in combination with a single layer of cholesterol structure to destroy or reduce the content of a single region of optically active agent by UV irradiation. 6 200941073 • The effect of colorization to a single layer. However, such displays are susceptible to ambient light and reduce their stability. U.S. Patent No. 6,741,321 discloses a liquid crystal display device which utilizes a known single-layer dual-substrate assembly structure method to perform split-channel liquid crystal injection, which tends to cause overflow of liquid crystals of different colors, thereby forming liquid crystal mixed colors, resulting in chromatic aberration. Fig. 1A is a schematic cross-sectional view showing a conventional single-layer color cholesteric liquid crystal display device. In Fig. 1A, the conventional single-layer color cholesteric liquid crystal display panel 2 includes a gap between the lower substrate 6 and the upper substrate 12 oppositely disposed. A fence structure 8 is disposed between the lower substrate 6 and the upper substrate 12, and is divided into a plurality of elongated color sub-pixel liquid crystal channels. The lower substrate 6 is provided with a first electrode 4 and an alignment layer 14, and the upper substrate 12 is provided with a second electrode 10 and an alignment layer 14, wherein the arrangement directions of the first electrode 4 and the second electrode 10 are perpendicular to each other. Fig. 1 is a schematic view showing the lower substrate of the single-layered cholesteric liquid crystal display device shown in Fig. 1. In the first diagram, the fence structure 8 separates a plurality of (R, G, Β) strip-shaped color sub-halogen liquid crystal channels CR, CG and CB. The orthogonal sections 16 and 18 are disposed in the liquid crystal channels CG and CB to be closed at one end. After the upper and lower substrates are assembled, the second end L2 of the fence structure 8 is sealed with a sealing material to completely close the liquid crystal channels CG and CB, and the liquid crystal channel CR is exposed to the first end Li as a liquid crystal injection port. Then, the color liquid crystals are sequentially poured into the liquid crystal channels Cr, Cg, Cb and sealed. However, before the traditional single-layer color cholesteric liquid crystal is filled, it is necessary to first seal the second end of the fence structure, and when the liquid crystal is injected, it is easy to cause different color liquid crystal overflow, 7 200941073 * and then form a liquid crystal color mixture, resulting in chromatic aberration phenomenon. Furthermore, a conventional single-layer cholesteric liquid crystal display is provided with a pretilt alignment layer between the liquid crystal layer and the upper and lower substrates. Obviously, the structure containing the alignment layer requires a large driving voltage and significantly reduces the contrast. SUMMARY OF THE INVENTION In view of the above, the present invention provides a color cholesteric liquid crystal display device and a manufacturing method thereof, wherein a fence structure is formed on a substrate to form a liquid @ crystal injection channel of different length, and the fence structure is a bonding layer or a coating. A layer of adhesive material is applied to the surface of the fence structure or a layer of patterned adhesive material is applied to the opposite substrate for assembly. By cutting and injecting red, green, and blue liquid crystals and sealing processes, liquid crystal overflow and chromatic aberration of different colors are avoided. Since each of the halogen regions has substantially no patterned bonding layer, the driving voltage can be simultaneously reduced and the contrast can be increased. An embodiment of the present invention provides a color cholesteric liquid crystal display device comprising: a first substrate and a second substrate having a gap therebetween; a patterned fence structure disposed on the first substrate and the second Between the substrates, a plurality of strip-shaped color sub-pixel liquid crystal channels are separated: and a plurality of colors of colored cholesteric liquid crystals are filled in the corresponding color-shaped color sub-halogen liquid crystal channels; wherein the patterned fence structure is a bond The layer or the patterned fence structure has a corresponding patterned bonding layer between the second substrate or the first substrate to prevent overflow of adjacent sub-pixel liquid crystal channels.

DETAILED DESCRIPTION OF THE INVENTION In order to make the present invention more apparent and easy to understand, the following detailed description of the embodiments and the accompanying drawings will be described in detail as follows: [Embodiment] FIG. 2A shows a single layer of color cholesterol according to an embodiment of the present invention. Flow chart for manufacturing a liquid crystal display device. Referring to Fig. 2A, a first step of fabricating a first substrate (e.g., a lower substrate) is performed, including providing a first substrate (S210), and forming a first electrode on the first substrate in a first direction (S212). Next, forming a patterned fence structure on the first substrate (S216), the patterned fence structure includes a plurality of wall structures, one end of each wall structure is orthogonal to a flat sealing end' to be isolated to have a a first liquid crystal channel of the first liquid crystal injection port, a closed second liquid crystal channel, and a closed third liquid crystal channel. Next, a fabrication step of the second substrate (e.g., the upper substrate) is performed, including providing the second substrate (S220), and forming the second electrode on the second substrate in the second direction (S222). Then, a bonding layer is formed on the surface of the patterned fence structure or is formed into a corresponding patterned bonding layer on the second substrate (S23〇〇). 10 200941073 • The first substrate and the second substrate are combined (S230), and the first substrate and the second substrate are opposed to each other when combined, and a gap is interposed therebetween. The patterned barrier layer is used to tightly bond the patterned fence structure to the second substrate to prevent overflow of the adjacent sub-halogen liquid crystal channel during subsequent liquid crystal infusion. Next, the first color cholesteric liquid crystal is poured and sealed (S240). The first slit is applied to expose the second elongated liquid crystal cell (S250), and the second color cholesteric liquid crystal is poured and sealed (S260). Next, a second cut is applied to expose the third elongated liquid crystal cell (S270), and the third color cholesteric liquid crystal is poured and sealed (S280). After the completion of the ® color liquid crystal channel filling step, the subsequent display panel process (S290) is performed. Since each of the halogen regions has substantially no patterned bonding layer, the driving voltage can be simultaneously reduced and the contrast can be increased. According to another embodiment of the present invention, in step S216, a patterned patterned fence structure can be directly formed on the first substrate. For example, forming an incompletely cured patterned photoresist fence structure (eg, a soft baked photoresist) on the first substrate, retaining its adhesive semi-solid state, after passing through the combination with the bottom two substrates, The patterned photoresist fence is fully cured (for example: hard-baked or light-cured photoresist). Thus, the step of forming the patterned bonding layer should be omitted, as shown in Fig. 2B. Fig. 3A is a schematic view showing the steps of combining the first and second substrates in an embodiment of the present invention. Referring to FIG. 3A, a patterned fence structure 340 is formed on the first substrate 360. The patterned fence structure 340 includes a plurality of wall structures separated into a first liquid crystal channel having a first liquid crystal injection port, a closed second liquid crystal channel, and a closed third liquid crystal channel. Each liquid crystal channel corresponds to a single-layer color cholesteric liquid crystal display. 200941073 • The prime region, the secondary halogen region includes a first substrate of a halogen electrode, such as a first electrode in a first direction. The patterned fence structure can be formed by any patterning process, such as lithography or screen printing, and the material can include a photoresist. The material of the first substrate comprises a rigid substrate or a flexible flexible substrate. For example, the flexible flexible substrate comprises a polycarbonate (PC) substrate, a polyethersulfone resin (PES) substrate, a polyethylene terephthalate (PET) substrate or a polyimide ( PI) substrate. The first substrate may include circuit elements for controlling the 10 pixel electrodes, such as a thin film transistor (TFT) and a capacitor. Next, a second substrate 310 is provided, which is made of a rigid substrate or a flexible flexible substrate. On the second substrate 320 is a second electrode in the second direction. The first electrode and the second electrode are substantially perpendicular to each other. Then, a bonding layer is formed on the surface of the patterned fence structure or a patterned bonding layer 330 is formed on the second substrate 310. The material of the patterned adhesive layer 330 includes a gelatinous material or a solid material. For example, the solid material comprises a photocurable material or a heat curable material. The thickness of the bonding layer 330 is less than the height of the patterned fence structure 340. Further, since the bonding layer 330 is substantially not patterned in each of the halogen regions, the driving voltage can be simultaneously lowered and the contrast can be increased. It should be noted that the patterned bonding layer may optionally be applied directly to the patterned fence structure of the first substrate, as shown in Figure 3B. By precisely positioning the control and ink jet technology, the bonding layer can be formed directly on the corresponding patterned fence structure. Then, the first substrate 360 and the second substrate 310 are oppositely combined, so that the patterned bonding layer 330 of FIG. 12 and the corresponding patterned fence structure 340 are tightly bonded, or the patterned bonding layer 330 is tightly coupled to the second substrate 310. The combination is to prevent overflow of the adjacent sub-halogen liquid crystal channel when the subsequent liquid crystal is poured. Fig. 3C is a schematic view showing the steps of combining the first and second substrates in another embodiment of the present invention. A cemented patterned fence structure 340' is formed on the first substrate 360. The patterned fence structure 340' includes a plurality of wall structures separated into a plurality of liquid crystal channels corresponding to the secondary halogen regions of the single layer color cholesterol liquid crystal display. Each of the halogen regions includes a first electrode of the pixel electrode, such as a first electrode along the first direction. The patterned fence structure can be formed by any patterning process, such as lithography or screen printing, and the material includes a photoresist material that has not been cured by hard bake. The material of the first substrate comprises a rigid substrate or a flexible flexible substrate. Furthermore, the first substrate may include circuit elements for controlling the pixel electrodes, such as thin film transistors (TFTs) and capacitors. Next, a second substrate 310 is provided, which is made of a rigid substrate or a flexible flexible substrate. An electrode ® 320 may be included on the second substrate 310, such as a second electrode in a second direction. Since the patterned fence structure 340' is inherently viscous, the patterned bonding layer can be omitted from the second substrate. Moreover, there is substantially no patterned bonding layer in each pixel region, so that the driving voltage can be simultaneously reduced and the contrast can be increased. Then, the first substrate 360 and the second substrate 310 are oppositely combined to make the adhesive patterned fence structure 340' and the second substrate 310 tightly combined to prevent the adjacent sub-halogen liquid crystal channel from overflowing during subsequent liquid crystal infusion. flow.
